HYDRQARBoN-BURNER.

. This invention relates to burners `for the combustion yof fuel forheating purposes, and

` especially to those whereby steam `or other suitable fluid underpressure and oil or other combustible fuel are mixed, atomized, and

discharged, combustion taking place at or near the pointf of discharge.r

Improvements are made by this invention in thetype of `burner shown inmy United States Letters Patent No. 792,265, issued June 13, 1905.

Simple and improved means'are provided by the s flow of either heavy orlight fuel isv produced and the fuel mixed and discharged with the fluidentering the burner under pressure, the elements being broughtl to theproper degree of heat during passage through the burner. The inventionfurther provides improvements in the details of structure and partswhereby an assembled device of few parts is produced which is simple,strong,I efficient,

and economical. A

The Adetails of construction and arrangement of parts contemplated bythis invention are disclosed in the accompanying drawings, forming parthereof, wherein a preferable embodiment of the invention is shown forpurposes of illustration and in which like reference characters refer tocorresponding parts in the several views, whereof- Figure 1 is an outerview of the burner. Fig. 2 is a central longitudinal sectional view.Fig; 3 is a cross-sectional view onthe. line z z, Fig. 2. Fig. 4 is across-sectional view on the line y y, Fig. 2; and Fig. 5 is across-sectional f view on the line a; Fig. 2.

Referring more particularly tothe drawings, 6 designates an koutercasing'or shell. This casin comprises an elongated portion 7 and an enarged portion S, the two portions being preferably integrally formed.The elongated portion 7 at its free end constitutes a part of thedischarge end ofthe burner, where it is interiorly contracted to formconverging surface 9, whereby the material pass- Specicaton of LettersPatent.

ing out of casing 6 is converged or contracted. Enlarged portion 8 formsa chamber 10, and through this portion of casing 6 is formed'an entrance11 to chamber 10, the entrance being interiorly rscrew-threadedv vforthe reception of a supply-pipe. The open or free-end 1'2 of casing 6 isinteriorly screw-threaded.

' Into the screw-threaded end 12-is screwed a vmember comprising anouter casing 13,y a-

substantially transverse portion 14, and an inner casing 15, these partsbeing integrally formed and producing a chamber 16 andk a continuouspassa e therefrom to the discharge end ofthe urner.

Casing 13 is preferably coincident in thickness and transverse dimensionwith portion 8 of casing 6, to which it is jointed at its reducedscrew-threaded part 17. It is interiorly screw-threaded at its other orouter end. Through casing 13 is formed an 'entrance 18 to chamber 16.

Portion 14 constitutes a transverse partition between chambers 10 and 16and is provided with an aperture or opening 19, saidopeninggradually'decreasing in width from chamber 16 to where it mergeswith the interior of inner casing 15.

Inner casing 15 extends from portion 14 and opening 19 through chamber10 andportion 7 of casing 6 to the discharge end of the burner. Theouter surface of the portion of casing 15 passing through ortion 7 isremoved from and substantial y parallel with" the inner surface ofportion 7 except at the.

discharge end, a'continuous passage between the two casings thus beingformed. At the discharge end casing 15 has a beveled exterior surface 20complementary to. surface 9 and with this latter surface forming aconverging opening. The interior of casing 15 gradually increases insize from opening 19 to the discharge end.

Into the outer end of casing 13 is'screwed a plug 21, formed with asquared outer end 22 to facilitate removal and having a thimble shapednipple 23 projecting through chamber 16 and into opening 19 and endingwhere casing 15 begins. The plug is formed with a centrally-disposedpassage 24, extending from end to end of the plug, screw- 'the side ofopening 19, and where it projects substantially IOO into opening 19, isof less width than said opening, a passage from chamber 16 to casing 15thus being left.

Steam or other suitable heated fluid is suppliedto the burner throughentrances 11 and 24, and oil or other fuel is supplied to chamber'16through entrance 18. The steam or other fluid comingthrough entrance 11enters chamber 10, surrounds casing 15, and passes out through portion7. Steam or other fluid entering through passage 24 is discharged at theend of nipple 23 into casing 15, where it induces How of fuel fromchamber 16 through opening 19 and atomizes and mixes With the fuel, themixture being carried by force ofwemission from the nipple throughcasing 15 and out of the burner. The interior of casing 15 graduallyincreasing in size from its receiving end to its discharge end, dangerof back pressure of fuel is obvi, ated. The fuel is first heated inchamber 16 by contact with nipple 23, through which steam or otherheated iuid passes, and the temperature of the mixture of steam or otherfluid and fuel is further raised to the proper degree during its passagethrough easing 15, which is surrounded and heated by the steam or otherheated iuid entering passage 11. At the discharge end of the burner thislatter supply of steam or other fluid is converged across and mixes withthe discharge of mixture from casing 15 by the converging surfaces 19and 20.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, iis- 1. A burner comprising an outer casinghaving an opening therein :a member attached to said outer casing andincludinga short portion forming a chamber having an opening thereto, anapertured transverse portion constituting a partition between saidchamber and the interior of said outer casing, and an inner casingextending from said apertured portion and its aperture through said.outer easing, a space being left between said inner and outer casings,and a plug fitted. into said short portion and comprising a nippleprojecting through said chamber and into the aperture in said aperturedportion, a passage being formed through said plug.

2. A burner comprising an elongated outer casing 3 an enlarged outercasing connected therewith, forming a chamber, and having an openinginto said chamber; a member attached to said enlarged casing, saidmember comprising a short portion forming a chamber having an openingthereto and joining said enlarged casing with which it is coincident inthickness and width, an apertured transverse portion forming a partitionbetween said chambers, and an inner casing extending from said aperturedportion and its aperture through said enlarged and elongated outercasings, a space being left between said inner and outer casings, and aplug fitted into said shortportion and comprising a nipple projectingthrough the chamber in said s wrt portion and into the aperture in saidapertured portion, a passage being formed through said plug.

In testimony whereof I afiix my signature 1n presence of two witnesses.
